完整圖錄內容
• Rarely seen retailer’s demonstration model of the 27-400 AM movement
• With original presentation box and loupe
The caliber 27-AM 400 (or 27-400 AM) was introduced in 1958 as an anti-magnetic manually-wound movement with an oversized balance wheel to answer demands for a utilitarian wristwatch that would endure the demands of certain occupations.
Based off of previous calibers, it was further upgraded with a Gyromax balance wheel to improve shock resistance and reduce air resistance and manufactured with anti-magnetic materials such as beryllium. Most notably, it was fitted to the anti-magnetic wristwatch produced by Patek Philippe, the reference 3417 (for an example of the ref. 3417, please see lot 23).
In order to better market and highlight their achievement, Patek Philippe created a series of demonstration kits for the 27-AM 400, showing both sides of the movement and displayed in a fitted red leather presentation box, as well as a loupe for closer inspection. These hardly ever appear at public auction and is a delightful and rare accessory for the devoted collector.
